The Eiffel Tower on Monday was lit in rainbow colors to remember the victims of Sunday's attack in Orlando, Florida.

Described as the deadliest mass shooting on American soil, 50 people died and 53 were injured when a lone gunman with possible connections to ISIS opened fire in an Orlando gay nightclub.

“Paris, city of equal rights, resolutely mobilized against homophobia. #Lovewins #Orlando,” Paris Mayor Anne Hidalgo tweeted along with a photo of the Eiffel Tower bathed in rainbow colors.

Hidalgo told the AFP that City Hall would also fly the U.S. flag and the rainbow flag to express “compassion, solidarity and affection” for the American people following the attack.

On Monday morning, Paris councillors observed a minute of silence for the victims of Sunday's massacre.

Last year, monuments around the globe, including One World Trade Center in New York, were draped in the colors of the French flag following a terrorist attack in Paris.
